T1 - Validation of submodels for CFD simulation of n-hexane pool flames including interferometry N2 - Computational fluid dynamics (CFD) simulation is used to predict transient and time-averaged glame temperatures and species concentrations of an n-hexane pool flame. Employing a combination of an assumed probability density function approach with laminar flamelets using detailed kinetic data and large-eddy simulation with Smagorinsky submodel is shown to be a promising way in modeling pool and tank fires. The measured species concentration and flame temperature profiles from gas chromatography, thermocouple measurements and holographic interferometry are used to validate the submodels for CFD simulation of pool flames.

A1 - Davis, M. A1 - Wehrstedt, Klaus-Dieter T1 - Taming the silicon tetraazide beast N2 - Highly energetic silicon tetraazide 1 is synthesized safely in high yield and high purity. The compound is prepared as a solution in benzene which allows it to be handled safely. Stable Lewis base adducts of Si(N3)4 (e.g. 2) are also prepared by treatment of either Si(N3)4 or the di­sodium salt of hexaazidosilicate (3) with Lewis bases (2,2-bipyridine or 1,10-phenanthroline). Unlike Si(N3)4 the Lewis base adduct 2 is thermally stable and does not decompose below 265 °C. The decomposition is very energetic (ΔHd = -2.4 kJg-1) which means 2 and related Lewis base ­adducts could replace environmentally harmful Pb(N3)4 used as primary explosive.
